Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, and in particular relates to a prefabricated sliding contact mobile support platform. Background Technology

[0002] The prefabricated sliding contact mobile support platform is a type of equipment used in fields such as tunnel construction. It mainly consists of a support structure, a propulsion device, and a sliding contact support device. The propulsion device is installed on the lower surface of the support structure, and the sliding contact support device is installed on the upper surface of the support structure.

[0003] When deploying the support rods of a conventional prefabricated sliding contact mobile support platform, it is necessary to stretch them into place, then apply force to the plug and pull back and forth until the holes are aligned, insert the plug and tighten it, and then tighten the nut. This makes the operation of the support rods of a conventional prefabricated sliding contact mobile support platform quite troublesome.

[0004] To address these issues, we propose a prefabricated sliding contact mobile support platform. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the operation of the support rods of conventional prefabricated sliding contact mobile support platforms is relatively troublesome, and to propose a prefabricated sliding contact mobile support platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated sliding contact mobile support platform includes a guide sleeve, an outer rotating seat of which a plug is slidably mounted. A sliding bolt is slidably inserted into the inner part of the guide sleeve. One end of the sliding bolt is fixedly connected to a bolt, and a nut is threaded onto the outer thread of the bolt. A first mounting seat is slidably mounted on the outer part of the bolt. The plug and the sliding bolt are interlocked. Pulling the plug upwards, rotating the rotating seat to move the plug away from the upper side of the sliding bolt, pulling the sliding bolt to adjust its length, and then operating the rotating seat to rotate the plug directly above the sliding bolt, and then tightening the nut to press the first mounting seat, as the sliding bolt retracts into the guide sleeve under reaction force, aligning the bolt's holes, the plug is inserted into the sliding bolt to lock it in place. Tightening continues until the first mounting seat is pressed firmly against the target, facilitating length adjustment for support.

[0008] Preferably, the guide sleeve includes a sleeve, one end of which is fixedly connected to a second mounting base, and the other end of which is fixedly connected to a sleeve-shaped bearing seat, with a sliding bolt slidably inserted into the sleeve and the sleeve-shaped bearing seat.

[0009] Preferably, the rotating seat includes a base, a guide seat fixedly connected to the upper end of the base, and a spring buckle fixedly connected to the upper end of the base. The base rotates and fits onto a sleeve-shaped bearing seat, and the upper end of the spring buckle engages with the sleeve-shaped bearing seat. By rotating the base, the guide seat is rotated, causing the pin to move away from the sliding bolt, allowing the sliding bolt to be pulled out without obstruction. Rotating the base back, the spring buckle engages with the sleeve-shaped bearing seat for positioning, positioning the pin directly above the sliding bolt. This allows the pin to automatically insert into the sliding bolt under gravity after its hole is aligned with the pin.

[0010] Preferably, the bolt includes a bolt body, a first limiting block is fixedly connected to the middle of the bolt body, and a plug rod is fixedly connected to the lower end of the bolt body. The plug rod is matched with the sliding bolt. The bolt body and the plug rod are slidably installed in the base and the guide seat, and the first limiting block is slidably locked in the guide seat. Pulling the bolt body upward causes it to act upward on the plug rod, pulling the plug rod away from the sliding bolt. Rotating the rotating seat causes the bolt and the sliding bolt to be misaligned, preventing the bolt from being inserted into the sliding bolt. Conversely, rotating the bolt back allows it to automatically insert into the sliding bolt, facilitating locking or unlocking of the sliding bolt.

[0011] Preferably, the bolt includes a bolt body, a second limiting block is fixedly connected to the outside of the bolt body, one end of the bolt body is fixedly connected to a sliding bolt, and a nut is threadedly installed outside the bolt body.

[0012] Preferably, the first mounting base includes a sliding sleeve, which is slidably sleeved outside the bolt body and the second limiting block. One end of the sliding sleeve is fixedly connected to the mounting base body. After the sliding bolt is pulled out, the bolt is turned upwards, and then the nut is tightened to press the first mounting base, so that the first mounting base presses against the target support plate, which facilitates fine-tuning and tightening of the support plate.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Pull the plug upwards, rotate the rotating seat to move the plug away from the upper side of the sliding bolt, pull the sliding bolt, adjust the length, and after adjustment, operate the rotating seat to move the plug directly above the sliding bolt. Then, tighten the nut to press the first mounting seat. When the sliding bolt is subjected to the reaction force and retracts into the guide sleeve, when the hole of the sliding bolt is aligned, insert the plug into the sliding bolt to lock the sliding bolt. Continue to tighten until the first mounting seat is pressed against the target, which facilitates length adjustment for support.

[0015] 2. Operate the rotating seat body, which drives the guide seat to turn. The guide seat rotates the plug away from the sliding bolt, allowing the sliding bolt to be pulled out without obstruction. Rotate the seat body back, and use the spring buckle to lock and position the plug with the sleeve bearing seat, so that the plug is directly above the sliding bolt. This makes it easy for the hole of the sliding bolt to be aligned with the plug, and then automatically inserted into the sliding bolt by gravity.

[0016] 3. Pull the bolt body upwards so that it acts upwards on the insert rod, pulling the insert rod away from the sliding bolt. Rotate the rotating seat to misalign the insert and the sliding bolt, preventing the insert from being inserted into the sliding bolt. Conversely, rotate the insert back so that it can automatically insert into the sliding bolt, making it easy to lock or unlock the sliding bolt.

[0017] 4. After pulling out the sliding bolt, turn the insert bolt upwards, and then tighten the nut to press the first mounting seat against the target support plate, so that the first mounting seat can be pressed into the target support plate for easy fine-tuning and tightening of the support plate.

The bolt 4 and the sliding bolt 7 are inserted and matched. Pull the bolt 4 upward, rotate the rotating seat 3 to rotate the bolt 4 away from the upper side of the sliding bolt 7, pull the sliding bolt 7 to adjust the length, and after adjustment, operate the rotating seat 3 to rotate the bolt 4 directly above the sliding bolt 7. Then, tighten the nut 1 to press the first mounting seat 6. When the sliding bolt 7 is subjected to a reaction force and retracts into the guide sleeve 2, when the hole of the sliding bolt 7 is aligned, the bolt 4 is inserted into the sliding bolt 7 to lock the sliding bolt 7. Continue to tighten until the first mounting seat 6 presses against the target.

[0027] like Figure 1 and 2 As shown, the guide sleeve 2 includes a sleeve 21, one end of which is fixedly connected to a second mounting base 22, and the other end of which is fixedly connected to a sleeve-shaped bearing seat 23. A sliding bolt 7 is slidably inserted into the sleeve 21 and the sleeve-shaped bearing seat 23. The sleeve 21 and the sleeve-shaped bearing seat 23 guide the sliding bolt 7 to slide, thereby adjusting the length of the guide sleeve 2 and the sliding bolt 7.

[0028] like Figure 1 , 2 As shown in Figure 3, the rotating seat 3 includes a seat body 31, a guide seat 32 fixedly connected to the upper end of the seat body 31, and a spring buckle 33 fixedly connected to the upper end of the seat body 31. The seat body 31 is rotatably sleeved on the sleeve bearing seat 23, and the upper end of the spring buckle 33 is engaged and matched with the sleeve bearing seat 23. By rotating the seat body 31, the guide seat 32 is rotated, and the guide seat 32 rotates the pin 4 away from the sliding bolt 7, allowing the sliding bolt 7 to be pulled out without obstruction. The seat body 31 is rotated back, and the spring buckle 33 is used to engage and position the pin 4 directly above the sliding bolt 7.

[0031] like Figure 1 , 5 As shown in Figure 6, the first mounting base 6 includes a sliding sleeve 61, which is slidably sleeved outside the bolt body 51 and the second limiting block 52. One end of the sliding sleeve 61 is fixedly connected to the mounting base body 62. After the sliding bolt 7 is pulled out, the plug 4 is turned upwards, and then the nut 1 is tightened to press the first mounting base 6, so that the first mounting base 6 presses against the target support plate.

[0032] Working principle: Pull out the plug 4 upwards, rotate the rotating seat 3 to turn the plug 4 away from the upper side of the sliding bolt 7, pull the sliding bolt 7 to adjust the length. After adjustment, operate the rotating seat 3 to turn the plug 4 directly above the sliding bolt 7. Then, tighten the nut 1 to press the first mounting seat 6. When the sliding bolt 7 is subjected to the reaction force and retracts into the guide sleeve 2, when the hole of the sliding bolt 7 is aligned, the plug 4 is inserted into the sliding bolt 7 to lock the sliding bolt 7. Continue to tighten until the first mounting seat 6 presses the target.
